Your MD state inspection includes your drive axle. How often do you think about your Subaru’s steering system? Have you heard any cracks or popping noises when turning or accelerating? In the case of this Forester, the protective rubber boot around the drive axle had torn, allowing the lubricating grease within to leave the steering system. Overtime this small tear not only expands but allows metal on metal contact of the CV joints and axle shafts. Additionally this is a safety item, a part of the Maryland State Inspection and requires replacement to pass.
